Bulk Silica Powder Supply for Coatings, Plastics & Industrial Manufacturing
KOSNANO supports industrial formulation teams with precipitated silica, fumed silica, spherical silica and customized particle size solutions for coatings, plastics, rubber and polishing applications.
As a professional silica powder manufacturer, we offer the highest quality industrial silica powder on the market. Our silica powder is produced using high-purity quartz sand or precipitation processes, with precise particle size control and surface treatment to extract stable, functional powders. This is a versatile raw material used in coatings, plastics, and various industrial formulations. Our silica powder is also an ideal alternative to fumed silica and organically processed powders, making it advantageous in cost-sensitive projects or where supply chain stability is paramount.
KOSNANO is a leading supplier of industrial silica powder in China, with over 30 years of experience in silica powder production and supply. All our silica products are certified to international standards and undergo rigorous batch consistency testing and application performance verification. Therefore, you can rest assured that we can provide your company with 100% stable and reliable industrial-grade silica powder.

Production of Industrial Silica Powder
At our silica powder production facility, we employ a multi-step process to ensure our products meet the highest standards. First, we source basic raw materials from high-purity quartz ore or silicate raw materials. After cleaning and pretreatment, the raw materials are fed into a reaction or grinding process. During this process, silica is processed into a specific particle size distribution through precipitation or grinding classification. This ensures the powder retains its ideal functional properties, such as oil absorption, porosity, or dispersibility.
Next, we classify and surface-treat the powder to remove impurities and adjust its hydrophilic or hydrophobic properties. Then, after air classification or drying, the powder is sent to a collection system for gas-solid separation and sieving to obtain a semi-finished product. Finally, we mix and homogenize different batches of semi-finished products to produce the final product, which is then packaged and delivered to our customers.




Wide Applications of Industrial Silica Powder
As a matting agent and anti-settling agent in coatings
As an opening agent and anti-blocking agent in plastic films
As a free-flowing agent in powder coatings
As a thickener in unsaturated polyester resins (e.g., for artificial marble applications)
As a reinforcing filler and thixotropic agent in adhesives and sealants
As a rheology control agent and abrasion resistance enhancer in inks
As a functional filler in composite materials
As a carrier and anti-caking agent in pesticides and fertilizers, etc.
